Foliar spay of zinc oxide nanoparticles (ZnO-NPs) is a common practice to provide the necessary Zn element for crops, which may also be a potential source for human expose to NPs with possible adverse health effects. Presently little is known about the forms and distributions of ZnO-NPs in plants after it is applied by foliar spay due to the lack of reliable quantification method. In this work, a complexed enzymatic extractant combined with single particle-ICP-MS system (SP-ICP-MS) was developed for simultaneously determining the concentrations and size distributions of ZnO-NPs in plant tissues. The measuring conditions were optimized and the method was applied to quantify ZnO-NPs uptake and distributions in rice plants after foliar application of ZnO-NPs. The results showed that the established method could well quantify the NP concentration in plant tissues with a detection limit of 16 nm; foliar spray of ZnO-NPs increased the Zn concentration (22.66  0.51 mg•kg -1 ) in rice grains by 447%, which was still within the limits of the food safety standard of China (NY 861-2004, 50 mg•kg -1 for Zn). ZnO-NPs larger than 60 nm cannot be directly absorbed by the leaves and may instead fall into the soil. ZnO-NPs with a size between 30-60 nm in the leaves could be retained due to the hindering effect of the cellulose-hemicellulose network. The smaller ZnO-NPs with size less than 30 nm could only be detected in stems but not in the grains, indicating that ZnO-NPs were dissociated or resolved as ionic form before they were transported into grains. The xylem and phloem were believed to be the organs responsible for the translocation and transformation of ZnO-NPs after being uptake by rice leaves. The study demonstrated the feasibility of the proposed method in characterizing NP behaviours in plants and proved the effectiveness and safety of foliar application of ZnO-NPs to rice.

UE to the rapid population growth, global food production should be increased to meet this global demand. Agriculture is considered the main dominant channel of food supply and any approach that support the crop productivity is urgent. These agro-practices may include using the high-yield varieties, improving rational irrigation and fertilization. It is noticed that, using of chemical or mineral fertilizers in agricultural production dramatically increased global food production. Several negative impacts have been recorded worldwide on the environment, which resulted from leaching of nutrients into groundwater, beside the low efficiency of applied fertilizers. Applying of nanofertilizers, is a promising approach, and an effective technology, which can increase sustainability and efficiency of agro-production of cultivated crops because of their nano-size properties, their high nutrient use efficiency, their slow release of nutrients, and thereby low required applied dose of fertilizer. Smart fertilizer means the control dose and time of applied fertilizers using the smart agro-technological and advanced tools such as global positioning systems, and remote sensing. These tools are able to maximize crop yield and minimize agro-chemical inputs by precise monitoring of the environment. Therefore, this work is a comparison between smart fertilizer and nanofertilizer, and to answer the main question: are the bio-nanofertilizers considered emerging precision agriculture strategy? This is also a call by Environment, Biodiversity and Soil Security (EBSS) for receiving articles on smart fertilizer, under many related topics such as different applications of smart fertilizers in smart agriculture, their challenges, their obstacles and the novel solutions in this concern.

“…These NPs swiftly dissolve into ions in soil systems, potentially enabling the reduction of nutrient application rates without diminishing yields, thereby promoting cost-efficiency and a minimized environmental impact (Sadhukhan et al, 2021;Akhtar et al, 2022;Nongbet et al, 2022;Kumar et al, 2023;Yadav et al, 2023). Earlier findings suggest that ZnO NPs contribute to improved nutrient uptake and yields in rice compared to traditional approaches (Adhikary et al, 2022;Sheikhnazari et al, 2023). Furthermore, a study by Yang et al (2021) demonstrated that ZnO NPs could enrich rice with elevated levels of essential nutrients such as N, P, and K. However, the practical application of NPs in field crop production presents challenges, mainly due to the complexities involved in administering smaller doses effectively.…”

In agricultural systems, significant nitrogen (N) losses from traditional fertilizers pose risks to food security and economic stability. An emerging approach to mitigate these losses involves nanoparticles (NPs) coatings onto urea, aiming to enhance N availability and consequently boost crop yields. To explore the most effective and sustainable N management strategies, a field experiment was carried out in Basmati rice at the ICAR-Indian Agricultural Research Institute, New Delhi, India over 2020–2021 in a split-plot design, with two summer green manure (GM) types-Sesbania (G2) and cowpea (G3) and fallow in the main plot and six nitrogen fertilization (NF) modules, i.e., 0 kg N + 5 kg Zn ha−1 through bulk ZnO (N1), N through prilled urea (PU) (N2), N through PU + 5 kg Zn ha−1 through bulk ZnO (N3), 1% bulk ZnO-coated urea (1% BZnCU) (N4), 0.1% nano ZnO-coated urea (0.1% NZnCU) (N5) and 0.2% nano ZnO-coated urea (0.2% NZnCU) (N6) in subplots replicated three times. The objectives of the study was to identify the optimal GM crops and the most effective NF modules on enhancing plant height, dry biomass, grain yield, milling quality, and N, P, K nutrition, as well as nitrogen use efficiency (NUE). Our findings demonstrated that, a significant enhancement in plant height (13.34%) and dry biomass (38.1%) at harvest was observed with the combined application of G2 and N6 when juxtaposed against G1 and N1. The pooled analysis revealed that GM enhanced grain yield by 12.75% in comparison to G1, irrespective of the NF modules employed. The Sesbania was identified as the top-performing GM, registering a yield 17.5% greater than fallow while it was 8.13% for cowpea. Among NF modules, there was a noted 10.03% yield increase when urea was zinc-coated compared to using only urea (N2), and a 33.75% increase against the N1. The application of N6 modules boosted hulling, milling, and head rice recovery by 3.73, 4.45, and 4.98%, respectively, compared to N1. Moreover, combining zinc with urea raised the N content in milled rice by approximately 9.1% and heightened the N, P, and K concentration in the straw by 22.8, 4.44, and 11.8%, and total N, P, and K uptake by 5.72, 3.33, and 11.7%, in comparison to the combined effect of N1 and N2. Considering the NUE metrics, such as partial factor productivity (PFP), agronomic efficiency (AE), recovery efficiency (RE), and physiological efficiency (PE), the application of GM showcased superior performance in PFP and RE against the G1, while AE and PE remained unaffected. The G2 as a GM, performed best in PFP and RE. The N5 module delineated the most substantial advancements in NUE indices, despite being comparable to N6. In conclusion, the adoption of Sesbania as a green manure crops, coupled with the 0.2% nano ZnO-coated urea module, is identified as an efficient method for maximizing growth, yield, milling attributes, nutrient assimilation, and overall NUE in the Basmati rice.
